I had never seen a fireball or meteor before. I was driving home from work and saw what I thought was a huge firework but when I saw how fast it going and the size of light I knew it was something astronomical. As quickly as it came into my sight of vision is as quickly as it left. If only I had a better vantage point I would have loved to be able to see it a bit longer. A very large bright green light with some red in the tail of it.
